Abstract (en)
[origin: EP3242288A1] A data drive circuit, a drive method for data drive circuit and an organic light emitting display that has the data drive circuit. The data drive circuit has a data signal multiplexing structure, and also comprises a power source line (50) for connecting to a power source (Vref) and second transistors (T2' ... Tm') connected to the power source line (50), the second transistors (T2' ... Tm') have source electrodes electrically connected to the power source line (50), gate electrodes electrically connected to the same line (Sel_1) of the control lines, and drain electrodes respectively electrically connected to different lines (Dj') of the signal lines at a connection point between a first transistor (T1 ... Tm) and the display area (40). By connecting a compensation power source (Vref) to the signal lines (D1' ... Dm') for initializing the pixel units (11 ... mm), the influence of stray capacitance in the pixel units (11 ... mm) is alleviated, thereby effectively improving the response properties and display properties of an organic light emitting display apparatus equipped with this data drive circuit.
